Specifications
The daisy chain power output option allows multiple MCC USB Series boards with a USB hub
output port to be powered from a single external power source in a daisy chain fashion.
The voltage drop between the input of one module and its daisy chain output is 0.5 V maximum.
You should plan for this voltage drop when configuring a daisy chain system to assure
functionality of the last board in the chain.
